A) Stroke volume
B) Cardiac output
C) Cardiac cycle
D) Systole

Accepted Answer

The cardiac cycle is the term used to describe the sequence of events that occur during one heartbeat, including the period of contraction (systole) and relaxation (diastole) of the heart chambers. Stroke volume and cardiac output are measurements of the amount of blood pumped by the heart per beat and per minute, respectively. Systole specifically refers to the period of contraction in the cardiac cycle.
